What's the operation's progress. (Read Only)

Return an operation's progress. (Read Only) This returns how close the operation is to finishing. The operation is finished when the progress float reaches 1.0 and isDone is called. If you set allowSceneActivation to false, progress is halted at 0.9 until it is set to true. This is extremely useful for creating loading bars.

See Also: isDone.

//This script lets you load a Scene asynchronously. It uses an asyncOperation to calculate the progress and outputs the current progress to Text (could also be used to make progress bars).

//Attach this script to a GameObject //Create a Button (Create>UI>Button) and a Text GameObject (Create>UI>Text) and attach them both to the Inspector of your GameObject //In Play Mode, press your Button to load the Scene, and the Text changes depending on progress. Press the space key to activate the Scene. //Note: The progress may look like it goes straight to 100% if your Scene doesn’t have a lot to load.

//Begin to load the Scene you specify AsyncOperation asyncOperation = SceneManager.LoadSceneAsync("Scene3"); //Don't let the Scene activate until you allow it to asyncOperation.allowSceneActivation = false; Debug.Log("Pro :" + asyncOperation.progress); //When the load is still in progress, output the Text and progress bar while (!asyncOperation.isDone) { //Output the current progress m_Text.text = "Loading progress: " + (asyncOperation.progress * 100) + "%";

// Check if the load has finished if (asyncOperation.progress >= 0.9f) { //Change the Text to show the Scene is ready m_Text.text = "Press the space bar to continue"; //Wait to you press the space key to activate the Scene if (Input.GetKeyDown(KeyCode.Space)) //Activate the Scene asyncOperation.allowSceneActivation = true; }
